| Post subject: | Engine options |
New to the page here. I'm sure this topic has come up before, but here goes. I have a 1992 SE that the engine is done. Can I use anything else but a L27 L code long block or are there any other options. I can find series II engines all day but the Series I are a bit harder to come by. Thanks |

If I remember right, 92 was a one year only upper aluminum intake manifold and no EGR setup. You should be able to use the block and heads from any 92-95 L27 though. (95 L27 being in Regals, vans, or whatever didn't get the L36 that year) Maybe you can just plug the EGR stuff and go on the 93-95s? Anything air/fuel related that's different I would swap over though. Injectors/MAF/Etc. |

My 92 had EGR. I always thought it was a mid-year change. Didn't some 92's also have Magnavox ignition? |

Yes, some 92's did come with Magnavox ignition systems. As mentioned, you will need to keep it L27. If you pull the engine from a later 93-95 with EGR, you'll likely need to swap the manifolds over, which you may as well do LIM gaskets anyway at that point. You can also get a donor car, and do a drivetrain swap, but that is a much bigger project than changing engines out. |

Not to question your credentials or anything, but why do you say the engine is done? What is the story on that, and also the service history of the car? |

I know this is an older post but I'm going to throw this out here... 91-92 L27 was 8.5 : 1 compression and 93-95 L27 was 9.0 : 1 compression.. You could use the 91-92 heads on the 93-95 block... 95 units used the series 2 crank and had a one year only balancer as well. |
